Pros
- Buffered formula reduces acidity, minimizing stomach discomfort
- Enhanced with bioflavonoids for improved bioavailability
- Third-party tested for quality and consistency
- Non-GMO and soy free for clean supplementation
- Affordable price point for a trusted brand

NOW Vitamin C-500 Calcium Ascorbate is a dietary supplement designed for individuals seeking a gentler form of vitamin C. Unlike standard ascorbic acid, this buffered version uses calcium ascorbate, which is less acidic and easier on the stomach. It is ideal for those who experience digestive discomfort with regular vitamin C, as well as anyone looking to support their immune system, skin health, and connective tissues.
The standout feature is the inclusion of bioflavonoids, plant compounds that work alongside vitamin C to enhance its antioxidant effects and absorption. This synergy helps protect cells from oxidative stress while promoting collagen synthesis, which is essential for skin elasticity, bone strength, and joint flexibility. Each capsule delivers 500mg of vitamin C, a moderate dose suitable for daily maintenance or as a base for higher intake.
The product is manufactured by NOW, a reputable family-owned company with over 50 years in the natural products industry. It carries a GMP Quality Assured certification, meaning every batch is tested in-house for potency, stability, and purity. The capsules are off-white and free from soy and GMOs, aligning with clean-label standards. The bottle contains 100 capsules, offering a convenient two-month supply at one capsule per day.
Potential drawbacks include the relatively modest vitamin C dosage per capsule, which may require multiple capsules for those seeking higher levels. Additionally, each capsule contains about 50mg of calcium, which could be a factor for individuals on calcium-restricted diets. As of this review, there are no customer reviews available, so firsthand experiences are limited.
Overall, NOW Vitamin C-500 Calcium Ascorbate is a well-formulated supplement for those who prefer a buffered, non-acidic vitamin C with added bioflavonoids. It offers solid quality and value from a trusted brand, making it a reliable choice for daily antioxidant support and collagen health.

This 8-ounce jar offers a generous supply of vitamin C powder, making it an excellent choice for individuals seeking to boost their immune system, support collagen production, or enhance antioxidant defenses.
The standout feature of this product is its pharmaceutical-grade purity. Free from common allergens like soy, gluten, dairy, and nuts, it is also vegan and non-GMO, catering to a wide range of dietary needs. The powder dissolves easily in water or juice, allowing for flexible dosing that can be tailored to individual requirements, whether you need a low daily maintenance dose or a higher therapeutic amount.
In terms of performance, users often report improved immune resilience and overall well-being with regular use. The antioxidant properties help combat oxidative stress, which is beneficial for maintaining healthy skin, joints, and cardiovascular function. However, the unflavored nature of the crystals means they have a tart, acidic taste that some may find unpleasant. Mixing with a strongly flavored beverage can effectively mask this.
As with any supplement, it is important to be mindful of dosage. Excessive intake of vitamin C can lead to digestive discomfort, such as diarrhea or cramps, particularly when taken on an empty stomach. Starting with a smaller dose and gradually increasing it, along with taking it with food, can help mitigate these effects.
Overall, NOW Supplements Vitamin C Crystals offer excellent value and quality. The brand's commitment to third-party testing and GMP compliance provides added assurance of purity and potency. For those seeking a versatile, high-quality vitamin C supplement, this product is a reliable and cost-effective choice.
